Do you know about the Separation of substances? If didn't know then just read the whole article. The separation technique is a method in which mass transfer takes place and converts a mixture of substances into two or more substances. Separation of substances is important in life because it keeps things separate which is helpful for every human being. For removing harmful things from your food items separation is necessary. Sometimes people used the substance in a single component then we use separation. Separation is used in different areas like the separation of stone from rice, the separation of husk from wheat, the separation of two liquids in the chemistry lab, and many more places. There are different types of methods of separation like handpicking, sieving, threshing, winnowing, etc. Do you want to know more interesting facts about the Separation of substances then start this quiz and know more about it.
